Givlaari's AWP remained the same again from March 2022 to December 2022, then increased again slightly in January 2023. Since January 2023, the AWP has remained consistent. The WAC has followed a very similar trend seeing slight bumps in March 2022 and January 2023, but otherwise remaining steady. The ASP has remained fairly close to the WAC, within $5-$10.
